A subset of the data obtained by featherston

The data in Table 8.3 are a subset of the data obtained by Featherston (1971). Among other things, he was interested in the relationship between the weight of tapeworms (Taenia hydatigena) fed to dogs and the weight of the scoleces recovered from the dogs after 20 days. (A scolex is the attachment end of a tapeworm, consisting of the head and neck.) The cysticerci used in the experiment were collected from sheep carcasses and force-fed to 10 dogs via gelatine capsules. The scoleces were recovered from each dog at autopsy, 20 days after the introduction of the tapeworms. Table 8.3 gives the mean weight of the initial cysticerci and the mean weight of the recovered worms for each of the 10 dogs in the study.

Test the hypothesis of independence versus the alternative that the mean weight of introduced cysticerci is positively correlated with the mean weight of worms recovered.
